Indeed the issue was that the gdm user was not a member of the video
group. Thank you!
I have verified the attached patch makes it sufficient to run
`modprobe uvesafb v86d=$(guix build v86d | head -n1)/sbin/v86d
mode_option=1280x800-32` before `herd restart xorg-server` without any
additional chmod. I will push if nobody objects.
I do however need to remove xf86-video-vesa via
set-xorg-configuration. Perhaps xf86-video-vesa should not be among
the defaults if uvesafb is to be made a default. Note that when not
running X as root, xf86-video-vesa does not work anyway. That’s what
uvesafb is for.
If uvesafb should be made a default, v86d:testvbe could be used to
find a suitable resolution as a mode_option parameter.
However I still do not know how best to modprobe uvesafb
automatically.
